Which expression represents the approximate length

Mathematics
1 answer:
Viktor [21]2 years ago
8 0

The expression that represents the approximate length of BC is; A: (3) sin(66)/sin (38)

<h3>Trigonometric Ratios</h3>

From the given triangle ABC, we see that;

∠A = 66°

∠C = 38°

AB = 3

Thus using sine rule, we have;

AB/sin C = BC/sin A

3/sin 38 = BC/sin 66

BC = (3sin 66)/sin 38

BC = 4.45

Cross section

Step-by-step explanation:

Cross section refers to the new two dimensional face exposed when we slice through a three dimensional objects.

It can also be the surface or shape exposed by making a straight cut through something, especially at right angles to an axis.

Cross section is the plane surface(two-dimensional objects) formed by cutting across a solid shape (three-dimensional shape) especially perpendicular to its longest axis.

A group of friends were working on a student film. They spent all their budget on props and costumes. They spent $693 on props,
sergeinik [125]

Answer:

The total budget is $1260

Step-by-step explanation:

Given

Props = \$693

Costumes = 45\%

Required

Determine the total budget

Since all budgets was spent on Props and Costumes only.

We have that.

\%Props + \%Costumes = 100\%

\%Props + 45\%= 100\%

\%Props= 100\% -45\%

\%Props= 55\%

In other words, 55% was spent on Props

Let the total budget be x, we have:

55\% * x = \$693

Make x the subject

x = \$693/55\%

x = \$1260

Hence, the total budget is $1260

How to solve 2x-y=17;x-y=10
Nataliya [291]
The answer is that y is equal to -3 and x is equal to 7 
2x-y=17
-2(x-y)=10 )
--------------
2x-y=17
-2x+2y=-20
----------------
y=-3

x-y=10 
x-(-3)=10
x+3=10
 -3   -3
----------
x=7
